Research to Prevent Damage of Aquatic Ecosystems

Anna University has worked on research and consultancy projects by adapting the latest technologies. Institute for Ocean Management has worked on the research project titled, “Coastal Morphodynamics and Environmental Variables of Ennore Creek: An Integrated Approach”, which helps to prevent the damage on Ennore creek. Institute of Remote Sensing having recognized by Government of Tamil Nadu as Tamil Nadu State Remote Sensing Applications Centre and Authorized Agency for Coastal Regulation Zone Mapping from Ministry of Environment, Forestry and Climate Change (MOEFCC), Government of India, has extensively contributed to the infrastructure development in various parts of the country, particularly along its long coast from Gujarat to West Bengal. Centre for Climate Change and Disaster Management, Anna University joined hands with Government of Tamil Nadu, established the 'Climate Studio' for the assessment of coastal hazards, vulnerability, and exposure along the Tamil Nadu Coastline to prevent the damage of aquatic ecosystems.

Coastal Morphodynamics and Environmental Variables of Ennore Creek: An Integrated Approach. Krishnaveni, M., Kalaivani, K., Priya, K. V., & Jagadish, C. (2023).

A social survey is conducted to identify the major environmental issues faced by the creek. The temporal variation of creek mouth and water quality are the major environmental issues that pose threat to the economic and health well-being of the fisheries community. The creek mouth plays a role in diluting the concentration of pollutants before they are mixed with seawater carried in by the tides. The temporal variations of different water quality parameters, such as pH, temperature, salinity, dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended solids (TSS), ammonium (NH4) and total nitrogen (TN), are analysed using the samples. The sampling results show the water quality of the creek is affected which may in turn affect the aquatic life.

INSTITUTE OF REMOTE SENSING

Having recognized by Government of Tamil Nadu as Tamil Nadu State Remote Sensing Applications Centre and Authorized Agency for Coastal Regulation Zone Mapping from Ministry of Environment, Forestry and Climate Change (MOEFCC), Government of India, Institute Of Remote Sensing has extensively contributed to the infrastructure development in various parts of the country, particularly along its long coast from Gujarat to West Bengal. With sophisticated infrastructure, skilled technical manpower and excellent support of University Administration, IRS is known as accurate, responsive, reliable service provider in the following domains.

• Coastal Regulation Zone Mapping
• Flood Inundation Mapping and Modelling
• Distance Certification from River, Interstate Boarders for Pollution Board Clearances

Research activities and Projects related to Coastal and Marine resources and management

1. Establishment of GIS Cell for Decision Support in Disaster Management and Populating NDEM with Disaster Specific Database and Integration of Storm Surge Model for Early Warning
2. Development of Biogeographic Information System for East Coastal of India Using Geospatial Technologies

CENTRE FOR CLIMATE CHANGE AND DISASTER MANAGEMENT

Operationalization of Climate Studio (with coastal risk assessment) sponsored by the Department of Environment, Govt. of Tamil Nadu

The Government of Tamil Nadu has established the 'Climate Studio' at the Centre for Climate Change and Disaster Management (CCCDM), Department of Civil Engineering, Anna University. The studio aims to provide updated high-resolution regional climate scenarios, assess climate change impacts on natural resources, develop and multi-sectoral spatial information, disseminate knowledge to stakeholders. The coastal risk assessment for the base period - (1992-2022) and the near century (2023 2050) was assessed using the components of coastal hazards, vulnerability, and exposure. The assessment of coastal hazards, vulnerability, and exposure along the Tamil Nadu Coastline has been determined by analyzing and integrating key indicators. The coastal areas of Tamil Nadu are highly vulnerable to various climate-related hazards such as sea level rise, cyclones, and shoreline changes.
